Problem solved!!!! I uninstalled the soundcard Realtech Audio HD. Then looked for changes in machine-configuration and found a the soundcard wich I reinstalled. That solved the problem. Thank's everybody!
Thank you all for trying to help. Unfortunately it didn't help much. I made a very easy test. Played a melody from Youtube on both computers simultanously and to my great surprise the computer "with the NWC-problem" sounded a semitone higher than than the other. So it's not a NWC-problem anymore. Now I have to find out why/how the soundcard has changed. But that's a different problem. Thank you! Hartmut
Thank you all for your suggestions. I have checked with AP Tuner. I don't know anything about the MultiPointController - have never used it. Think I have checked everything and this problem has emerged recently. I can't remember having this problem earlier. On my other computer I don't have this problem playing NWC-sheets.
Still - can there bee any settings in NWC or somewhere else which may cause this problem?
Hello, has anyone ever faced this problem: A note played from the NWC-sheet or on the NWC-keybord sounds a semitone to high compared to a tuner. A NWC-"C" sounds as a "C#" etc. No transposition is made, so that's not the reason. What other reason(s) can there be?
